A load flow method for weakly meshed distribution networks using powers as flow variables

The relationship between the branch powers and the node-injection powers were developed with the node-branch incidence matrix. Then based on two accurate formulas to estimate the voltage drop and angle difference, a new load flow algorithm for weakly meshed distribution systems was presented. By using active and reactive power rather than complex currents as flow variables, the algorithm reduces the computational complexity and has higher efficiency. Moreover, in order to deal with the PV nodes, a new solution was introduced based on Thevenin’s equivalent circuit. The solution deduced an accurate calculation formula to update the reactive power injections of PV nodes at each iteration and to fix voltage magnitude of PV nodes at specified values. The proposed load flow algorithm is essentially still belongs to the loop-analysis based method and has a strong ability to deal with meshed network. It reduces the iteration number and has a faster calculation speed even when network becomes more meshed and has more PV nodes. The numerical tests proved that the new method is robust and has excellent convergence characteristics.

Un détail de ce qui change: Function of a Function

Why should computation be leading to a bifurcation in architectural detailing, resulting in a simultaneous, and opposing, tendency towards either greater precision in fabrication or increasing plasticity? Architectural designer and theorist Peter Macapia asks what is driving these propensities in computation, and what in turn historically might be the relation between the detail and force. What comes into play now, though, when architectural style is no longer identified by a taxonomy of parts, or a vocabulary of orders, but rather by a network of forces and functions correlating actions? How might economic and political power be interacting with force, the diagram and function in contemporary design?     

Detailing the Walled Garden for Lebbeus

Neil Spiller , the Hawksmoor Chair of Architecture and Landscape and Deputy Pro Vice Chancellor of the University of Greenwich, London, has an unrivalled international reputation for the virtuosity of his visionary graphic work. Here, in a highly personal and poetic eulogy to Lebbeus Woods, Spiller pays tribute to his master through the lens of his own work, where detail becomes an important element in an imagined, augmented world in which the concrete or the specific lends credence to the fictional.     

Digital Doppelgängers: Future Scanscapes

Over the course of the last two years, ScanLAB Projects have explored various fragments of the natural and man-made world through the eyes of their forensic measuring machine. From surface mapping of Arctic ice floes in the Fram Strait (gateway to the Arctic) to the documentation of torture and detention sites in the Balkans, via the accidental editing of a Richard Long sculpture, to purposeful acts of detail theft from Foster and Wren. Here, Matthew Shaw and William Trossell discuss the capture, analysis and refabrication of their digital architectural doppelgängers.     

Animating Architecture: Coupling High-Definition Sensing with High-Definition Actuation

Ruairi Glynn , lecturer on interactive architecture at the Bartlett School ofArchitecture, University College London (UCL), puts the pressing question: ‘What does a world of hyper-connective, high-definition sensing offer architectural design?’ Despite the pervasiveness of ubiquitous computing – the Internet of Things (IoT) – and students' ability to speculate, build and test responsive lifesize installations, could practice itself be in danger of getting left behind?
